What's up with Light

• Radiant energy
• examples of light as energy

• Electromagnetic Spectrum

• Wave Characteristics
• Wavelength- distance between two similar points on a wave
• symbol: llamda λ 
• unit: meter
  
• Amplitude- distance between midpoint and peak or valley
• Frequency- number of waves that pass a point per second
• symbol: nu ν
• unit: waves/sec, Hertz (Hz) , 1/sec
• Speed- distance travelled per secon
• All electromagnetic waves travel at the same speed
• Speed of light (c) = 3.00 x 10⁸m/sec
• Relationship between frequency and wavelength
• If wavwes trael at the same speed as wavelength increases frequency decreases
  
• c= λ  ν
